Here is a recipe to make pancakes without wheat flour.

This is how I do them, this is the result of some trial and error and reading other's recipes.

Ingredients

Ratios by weight:

• 2.5 part milk
• 2 part milled or rolled oats. Sometimes I buy the rolled oats and then use the blender or something to make it like grounded oats
• 1 part egg
• 3%/oats baking powder (I'm not sure if this is too much, but it works)

Ingredients for 1L milk, ~20 pancakes, you can freeze them:

• 1L milk
• 800gr milled or rolled oats
• 400gr egg (I use 8 eggs, as the one I buy are ~50gr each)
• 25g Baking powder

Extras, add as you wish:

• Honey and/or sugar
• Oil
• Peanut butter
• Vanilla
• A pinch of salt

Steps

Main idea: mix liquids and solids separately, then mix them, then cook them.

1. Beat the eggs, there should be bubbles (air)
2. Add the extras you like to the eggs, such us honey and vanilla, and continue beating
3. Pour the milk into the mix, continue mixing/beating it
4. In another bowl mix the solids, the oats, the baking powder, and extras like sugar and maybe a bit of salt
5. Little by little add the solids to the liquids, mixing them. Now you have 1 bowl with the batter
6. Let it rest some time, 30 minutes or 1 hour. Keep it at room temperature
7. Preheat the pan, but once it is heated turn it down, almost completely off. This depends, in my case I have to put it almost off, very little fire. My experience is that low heat takes longer but I don't burn the pancake
8. Put some batter in the pan, flip it when the borders are cooked. You'll have to try and test when to flip it so that it can be flipped and it isn't burned

Key Points

The final batter shouldn't be liquid (add oats in that case), and shouldn't be solid neither (add milk/water in that case). Be aware that letting it rest for a while will make the batter more solid. You'll have to adapt and use more or less oats. Once you put some batter in the pan, it should slowly spread and make a circle by itself.

I managed to make them fluffy by using a lot of baking powder, beating the eggs for a long time, and using a very low heat when cooking.

You can make a lot of pancakes in one go, and freeze them.
